EL Resolver throws InvocationTargetException (char-long conversation)

for the jsf-source
Line 57: <h:graphicImage value="/images/#{personenBean.aktuellePerson.geschlecht eq 'w' ? 'fe':''}male.png"></h:graphicImage>

and the bean
public class Person implements Serializable {
	@Column(name = "\"geschlecht\"", nullable = false, length = 1)
	private char geschlecht;
...

MyFaces 2.1.7 throws
java.lang.reflect.InvocationTargetException
Caused by:<br/>javax.el.ELException - Cannot convert w of type class java.lang.String to class java.lang.Long
 at org.apache.el.lang.ELSupport.coerceToNumber(ELSupport.java:304)
personen.xhtml at line 57 and column 92    value="/images/#{personenBean.aktuellePerson.geschlecht eq 'w' ? 'fe':''}male.png"

Why does it try to convert the char 'w' to a long values although the referenced field is a char value?

downgrading to Apache Tomcat 7.0.25 did it. So it may be an issue with Tomcat 7.0.27.

sorry for missing to indicate the versions: I am using tomcat 7.0.27, primefaces 3.3, myfaces 2.1.17, weld 1.1.8

Hi,

this is not a Myfaces issue, but bug in EL implementation. You can see
org.apache.el.lang in stack = tomcat EL implementation.
Do you use tomcat  < 7.0.8 or WAS < 8.0.02? If so, please upgrade. See
[1] [2] and [3] for details.
